Abstract: At the admission section of a radially symmetrical longitudinal flow heat exchanger, cross flow of the tubes occurses. The cross flow is followed by an inclined flow, which turns over to a well-balanced longitudinal flow along the tubes. At two heat exchanger models (tube pitch S$_{\triangle}$ = 1.5, S$_{\triangle}$ = 2.0) the velocity distribution, the pressure-drop and the heat-transfer is determined experimentally. By the variation of the boundary- conditions, the influence of the geometrie, the mass flow, the tube pitch and the position of the first spacer is shown in this investigation. Finally the experimental datas are compared with results of calculations.
